I have a question about the estimation of standard error estimates of

Dear list,
I have some trouble generating a frequency table over a number of vectors.
Creating these tables over simple numbers is no problem with table()

1 3 4 5

Dear R-users,
I was wondering if anybody knows if it's possible to obtain a p value
for the full model of a GLMM with the lme4 package. I was told that I
should check whether the full model including all the predictor
variables is significant before doing stepwise regression or further

You can easily get rid of 0-frequency rows afterward.

This is a feasible solution only in lower dimensions; the area of the

Another possible approach (again in two dimensions) could be based
on the following.
First, if A, B, C are the vertices of a triangle, let (w1,w2,w3)
be sampled from the 3-variate Dirichlet distribution with index
(shape) parameters (1,1,1).
Hi, All;
A question not related to R.
I tried to use the biometrics Latex template from the journal homepage and
found it does not work. Does anyone mind sharing your well-worked latex
template? And I use Latex under Windows XP.
Thank you in advance for your help.

I'm glad the previous replies helped you solve your problem.
I think your original problem, though,
was caused by a typo. Note
the comma between the month and the year in your script and

I need to concatenate data frames that do not have all the same variable

Hi Andy,
I hadn't realized such objects (list matrices, list arrays, data frames with
nested lists) existed before, but now that I do I am seeing the documentation
with new eyes. I see that the pages for sapply(), lapply(), and class
coercion functions are true to their word.
Thanks,
Stephen
